The Agency works at facilitating the free movement of European products and services worldwide. This can be achieved by assisting third country regulators certifying European products and service providers. Reciprocally European certificates can be issued on the basis of third country certificates when there is sufficient confidence in the regulatory system of partner authorities to use their findings. To do so, bilateral agreements or working arrangements have to be concluded by the EU or the Agency, depending on the nature of the subject to be covered. The Agency assists therefore the Commission in the negotiation of agreements that have to bind the EU and its Member States or negotiates directly the arrangement covering its own field of activities.
